assignors to The National Cash Register Company, Dayton, Ohio, a corporation of Maryland Filed Jan. 17, 1962, Ser. No. 166,848 8 Claims. (Cl. 235-603) This invention relates to cash registers and accounting machines and is particularly directed to the totalizerselecting equipment of such machines.

It is a general object of this invention to provide improved means for selectively positioning a plurality of sets of totalizer elements on a common support in engaging relationship with the amount actuators.

Another object is to provide power means to shift a common support, having a plurality of sets of totalizer elements mounted thereon, from a central position in either of two directions to aline the selected set of totalizer elements with the amount actuators.

Still another object is the provision of power means to shift a common support, having a plurality of sets of totalizer elements mounted thereon, from a central position in either of two directions to aline the selected set of totalizer elements with the amount actuators, and further to provide manual means superseding the power means to shift the support from said central position in either of said two directions to aline the selected set of totalizer elements with the amount actuators.

A further object is to provide a machine having a plurality of sets of totalizer elements on a common support with power means effective in adding operations to selectively shift the support from a central position in either of two directions to aline the selected set of totalizer elements with the amount actuators and to further provide manual means effective in total-taking operations to supersede the operation of the power means, to selectively shift the common support from said central position in either of said two directions to aline the selected set of totalizer elements with the amount actuators.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.

The present invention is directed to a well-known type of cash register or accounting machine which is compact in overall dimensions and economical in construction but which nevertheless has many of the appointments and features of larger and more costly machines.

The machine chosen to illustrate the present invention is similar in appearance and in many structural details to the machines disclosed in Letters Patent of the United States No. 2,880,930, issued April 7, 1959, to Frank R. Werner et al.; No. 2,911,141, issued November 3, 1959, to John M. Jackson et al.; and No. 2,962,209, issued November 29, 1960, to Frank R. Werner et al., to which patents reference may be had for a full disclosure of the general construction of the machine and mechanisms which are not pertinent to the present invention and which for that reason Will be described only in a general way herein.

Mechanism pertinent to the present invention will be described in detail in the ensuing pages.

GENERAL DESCRIPTION The mechanism of the machine chosen to illustrate the present invention is mounted on and between right and left side frames, only the right frame 24 being shown in FIG. 2, said frames being mounted in vertical parallel relationship with each other on a machine base and properly spaced apart by various cross frames, rods, and shafts. The machine base is secured to a shallow pan which in turn is attached to the top surface of a drawer cabinet having therein the number of cash drawers required for the business system to which the machine is being applied. The mechanism of the machine is enclosed in a suitable case or cabinet, which is secured to the machine base.

None of the parts mentioned above, with the exception of the right frame 24, are disclosed herein, as they constitute no pertinent part of the present invention; however, reference may lbfi had to the patents referred to above for a full disclosure of said parts.

Referring to FIG. 1, the keyboard of the present machine has a Row 1 of control keys, comprising eight Clerks keys 25 and an Item Sub-Total key 26; a Row 2 of control keys, comprising nine Department keys 27; four denominational rows of amount keys 28; a release lever 29, for releasing any inadvertently-depressed amount key 28 prior to operation of the machine; and a total control lever 30, often referred to as a unit lock lever, for controlling the various functions of the machine, as will be explained more in detail later.

The two rows of control keys 25, 26, and 27 are mounted in a control bank framework (not shown), which is in turn removably attached to shafts (not shown) extending between the two main frames, and each row of amount keys 28 is mounted in a corresponding key frame (not shown), which likewise is removably supported on said shafts, the same as the control bank. The upper ends of the keys 25, 27, 27, and 28 extend through suitable openings in a keyboard top plate 31, which is in turn secured to the machine framework. The key release lever 29 also extends through a clearance slot in said plate, and an opening is provided in said plate, through which the total control lever 30 is accessible. The total control lever 30 has a lock 32, with suitable keys, for use in moving said lever to its various positions and also for locking said lever against manipulation by unauthorized persons.

Each of the rows of amount keys 28 is provided with a differential mechanism, similar to that disclosed in the patents referred to hereinbefore, comprising a primary differential member or amount actuator 33 (Fig. 2) and a corresponding secondary differential member (not shown), said primary member being positioned under control of the depressed amount key of the same denomination, and said secondary member being positioned in accordance with the positioning of said primary member and in turn transmitting its positioning to corresponding sight indicators (not shown), located in the upper portion of the machine, and to corresponding type wheels (not shown), for recording the value of said depressed amount key on suitable record material, such as a detail or journal strip, an issuing receipt, and/or an insertable slip.

Each of the two transaction or control rows containing the keys 25, 26, and 27 has associated therewith a differential mechanism, similar in every respect to the amount differential mechanism, for transmitting data corresponding to the depressed control keys to corresponding indicators and type wheels for the purpose of indicating and recording said data.

The present machine is provided with two lines of totalizers, a lower or No. 1 line, a fragment of which is shown in FIG. 2 and indicated generally by the reference number 34, said totalizer comprising eight sets of interspersed totalizer wheels 35 corresponding to the eight Clerks keys 25 in Row 1 and selected by said keys for alinement with the primary differential members 33. In addition to the eight sets of totalizer wheels corresponding to the Clerks keys 25', the No. l or lower totalizer line also includes a set of item totalizer wheels 36, located centrally in relation to the totalizer wheels 35 of the same denominational order, said item totalizer wheels normally being in alinement with the primary differential members 33, as shown in FIG. 2.

The No. 2 or upper totalizer line (not shown) cornprises nine sets of interspersed totalizer wheels, which are selected under control of the Row 2 Department keys 27, in exactly the same manner as explained fully in the Jackson et al. United States Patent No. 2,911,141.

The keys 25, 26, and 27 (Fig. 1), in addition to performing their other functions, are what are termed in this art motorized keys, in that depression of any one of these keys initiates operation of the machine.

Total izer-S electing Mechanism The present application is directed particularly to the mechanism for shifting the No. l or lower totalizer line (FIG. 2) laterally under control of the Clerks keys 25 to aline the corresponding sets of wheels 35 thereon with the primary differential members 33, and this mechanism will now be described in detail.

Each of the control keys 25, 26, and 27 and the amount keys 2% has, encircling its stem, the usual compressible spring (not shown), which springs urge said keys upwardly to undepressed positions. Depression of any one of the Row 1 control keys 25 or 26 (FIGS. 1 and 3 causes a pin 37 or 38, carried respectively thereby, to engage a corresponding curved slot in a machine release detent (not shown) and shift said detent to initiate machine operation, in the usual manner. The detent retains the key depressed until near the end of machine operation, whereupon restoration of said detent frees the key for return to undepressed position by its spring. The Row 2 control keys 2'7 coact with a corresponding machine release detent in exactly the same manner as the Row 1 keys.

Each denominational row of amount keys 28 is provided with the usual corresponding flexible detent (not shown) with hooks which coact with pins in said keys to retain said keys in depressed position during machine operation. Near the end of machine operation, the flexible detents are rocked to disengage the hooks from the pins of the depressed keys to permit said keys to be spring-returned upwardly to undepressed positions.

The pins 37 in the Row 1 Clerks keys 25 (FIG. 3) coact with totalizer-selecting surfaces formed by notches in the periphery of a totalizer-selecting segment 39 free on a main differential shaft 49 journaled in the machine framework. A toothed rearward extension of the segment 39 engages corresponding teeth in a gear 41 free on a stud 42 secured in a bracket 43 in turn secured to the outer face of a right totalizer support plate 49 (Fig. 2) secured to the right frame 24. There is a left totalizer plate (not shown), similar to the plate 49, for supporting the left-hand end of the totalizer mechanism. The gear 41 (FIG. 3) has integral therewith a bevel gear 44, which meshes with teeth in a bevel pinion 45 positioned at right angles thereto and free on a stud 46 secured in the bracket 43. Integral with the bevel pinion 4S and also free on the stud 46 is a wide-faced segmental gear 47 (F168. 2 and 3), the teeth of which mesh with rack teeth formed in the right-hand end of a totalizer-selecting shaft as, which is slidably supported in bushings in a totalizer framework comprising right plate 5% and a similar left plate (not shown), which plates are secured together for unitary shifting movement for the purpose or" engaging and disengaging the No. 1 totalizer wheels 35 and 36 with and from the primary differential members or amount actuators 33. The wheels 35 and 36 (FiG. 2) of the No. 1 totalizer are rotatably supported on a sleeve 51, which in turn is adjustably secured to the totalizer-selecting shaft 48 and is shifted longitudinally in unison therewith to aline the selected set of totalizer wheels with the amount actuators 33.

The segment 39 (FIG. 3) carries a stud 54, which pivotally supports the lower end of a totalizer-shifting arm 55, the enlanged upper end of which has an opening 56 with three sets of control surfaces formed therein for properly operating the segment 39 to in turn select the set of totalizer wheels 35 corresponding to the depressed Clerks key 25, as will be explained later. The control surfaces in the :opening 56 coact with flatted portions of studs 57 and 58, secured, respectively, in the forward arms of companion scissors levers 53 and 60 free on a stud 61 secured in the machine framework. The rearward arms of the scissors levers 59 and 60 have, respectively, formed on their inner edges, angular camming surfaces 62 and 63, which cooperate with a roller 64 secured to the upper arm of a hell crank 65 free on a stud 66 fast in the machine framework.

The bell crank 65 carries a stud 67 (FIG. 3), to which is pivotally connected the upper end of a link 162 carrying studs 163, which engage slots 164 in a companion link 165, the lower end of which is pivotally connected .to a stud 166 in a rearward arm of a lever 167 free on a stud 68 secured in the machine framework. The lever 167 carries rollers 69 and 70, which cooperate, respectively, with the peripheries of companion plate cams 71 and 72, secured on a main cam shaft 73 journaled in the machine framework and driven one clockwise rotation (FIG. 3) each machine operation, for the purpose of operating the mechanisms of the machine. A spring 74, tensioned between the companion links 162 and 165, urges said links inwardly, or towards each other, to form a yieldable operating connection between the cam lever 167 and the bell crank 65, for the purpose of properly expanding the scissors levers 59 and 60-, against the action of a spring 88, tensioned between said levers, as will be explained presently.

The shifting arm 55 (FIG. 3) has a slot 75 engaged by a roller 76 caried by a crank 77 free on a shaft 78 journaled in the machine framework. The crank 77 carries a stud 79 engaged by a notch in a shifting arm positioning segment 80 free on the shaft 40 (FIG. 5) and having, along its periphery, camming notches which coact with the pins 37 in the Clerks keys 25 and with the pin 38 in the Sub-Total key 26. A spring 81 (FIG.

3) urges the arm 55 counter-clockwise to normally maintain the right-hand, or No. 1, control portion of the opening 56 in alinement with the flatted studs 57 and 58 and, through the crank 77, urges the segment 80 also countepclockwise to normally maintain a finger 82, formed on said segment, in yielding engagement with the pin 37 in the A Clerks key 25, as shown here.

A downward portion of the segment 39 (FIG. 3) has a V-shaped alining or restoring notch 83, engaged by a roller 84 carried by an aliner or restoring arm 85 free on a stud 86 secured in the machine framework. A spring 87 urges the arm 85 counter-clockwise, causing the roller 84, in cooperation with the notch 83, to normally maintain the segment 39 in its central position, in which the wheels 36 (FIG. 2) of the item totalizer are in alinement with the primary diiferential members 33 for actuation thereby.

The Row 1 keys 25 are what are termed item total keys, in that they are used in the final item total operation of a multiple-item transaction to cause the item totalizer 36 to be cleared in the first part of the operation and to cause the amount cleared from said item totalizer to be transferred to the set of totalizer wheels 35 corresponding to the \depresed Clerks key 25 in the latter part of said operation.

Shifting-Segment-Restoring Mechanism In addition to the spring 87 (FIGS. 3 and 7), mechanism is provided for rocking the aliner arm 85 counterclockwise, at the beginning of item total and other operations, to positively engage the roller 84 with the alining notch 83 to insure that the segment 39 is restored to its central position to aline the item totalizer wheels 36 (FIG. 2) with the primary differential members 33 for clearing thereby in the first part of said item total operation. After the item totalizer wheels 36 have been cleared, the arm 85 is then rocked clockwise, against the action of the spring 87, to disengage the roller 84 from the notch 83 to counteract the action of the spring 87 and thereby facilitate the positioning of the segment 39 by the scissors levers 59 and 60, as will be explained presently.

A downward extension of the arm 85 (FIGS. 3 and 7) carries a stud 90, a flatted portion of which extends outwardly and coacts with a downward projection 91 formed on a disabling arm 92 having a slot which freely engages the circumference of a hub 93 carried by the arm 85, said hub rotatably supporting said arm 85 on the stud 86. A slot in the upper end of the arm 92 (FIGS. 7 and 8) engages a stud 94 carried by a disabling pitman 95, having a slot which freely engages the circumference of a bushing 193 on the stud 86. A spring 96, tensioned between a stud in the pitman 95 and a stud 97 in the arm 92, urges said parts towards each other to normally maintain said stud 97 in yielding engagement with an alining notch in said pitman 95, for the purpose of maintaining proper relationship of said parts. An inwardly-extending portion of the stud 90 engages a slot in the pitman 95 for the purpose of maintaining said pitman and the aliner arm 85 in proper relationship. A slot in the lower end of the pitman 95 (FIGS. 7 and 8) engages a stud 98 in a pitman-operating lever 99 free on a stud 100 secured in the right main frame. The lever 99 carries a roller 101, which coacts with a camming surface 102 on the lower end of a lever 103 free on the shaft 40. The upper end of the lever 103 (FIG. 7) has a slot which engages a stud 104 in a crank 105 secured on a totalizer control shaft 106 journaled in the machine framework. Also secured on the shaft 106 is a crank 107 having a stud 108, which engages a slot formed in the rear portion of the total control lever 30.

The arm 92 has, on its forward edge, a surface 109, arranged to coact with a stud 110 in an upward extension of a cam lever 111 free on the shaft 68. The stud 110 also enacts with a downwardly-extending finger 112 on the restoring arm 85. The lever 111 has a cam surface, indicated generally by the reference numeral 113, which coacts with a stud 114 on the inner face of the plate cam 72 secured on the main cam shaft 73 and driven thereby one clockwise revolution (FIG. 7) each machine operation.

The machine as disclosed herein is arranged for multiple-item transactions, comprising one or more itementering operations, under control of the Department keys 27 (FIG. 1) in Row 2, and a final item total operation, under control 'of the Clerks keys 25 in Row 1. The proper position for the total control lever 30 in multipleitem transactions is Register position, in which the projection 91 on the arm 92 is in the path of the fiat portion of the stud in the arm 85, as shown in FIG. 7.

In item-entering operations, depression of a Department key 27, through mechanism similar in every respect to that disclosed in the Jackson et al. United States Patent No. 2,911,141, immediately shifts the corresponding set of wheels on the No. 2, or upper, totalizer line into alignment with the primary differential members 33 to receive the amount of the item. In an item-entering operation, no Clerks key 25 in Row 1 is depressed, so the shifting arm 55 (FIG. 3) remains in its left-hand position, as shown here, in which the right-hand or No. 1 portion of the opening 56 is in alinement with the fiatted portions of the studs 57 and 58 in the scissors levers 59 and 60.

Initial movement of the cam 72 (FIGS. 3 and 7) causes the stud 114 to engage a projection 116 formed in the surface 113, to rock the lever 111 clockwise, causing the stud to engage the surface 109 and rock the arm 92 and, through the projection 91 and the stud 90, the restoring arm 85 counter-clockwise. Counter-clockwise movement of the arm 85 causes the roller 84, in cooperation with the notch 83, to insure that the segment 39 is fully restored to its central position, in which the central set of wheels 36 for the item totalizer (FIG. 2) are aligned with the primary differential members 33, to receive the amount of the item set up on the amount keys 28, in item-entering operations. Continued rotation of the cam 72 causes the stud 114 to engage a downwardlyextending finger 117 of the lever 111 to rock said lever counter-clockwise, causing the stud 110 to engage the finger 112 and rock the arm 85 clockwise to disengage the roller 84 from the notch 83 in the segment 39. The arm 85 and the roller 84 are retained disengaged by the finger 117, during the time that the segment 39 is being shifted in item total operations, for the purpose of relieving tension on said segment 39, so that it may be more easily shifted by the power mechanism shown in FIG. 3, as will be explained presently. However, this disengagement of the arm 85 is on no effect in item-entering operations, as the segment 39 remains in its central position throughout such operations.

While the arm 85 is retained disengaged, the cams 71 and 72 (FIG. 3) impart upward shifting movement to the companion links and 162, and they in turn rock the bell crank 65 clockwise. This causes the roller 64, in cooperation with the camming surface 62 and 63, to expand the scissors levers 59 and 60 against the tension of the spring 88, whereupon the studs 57 and 58, cooperating with the right-hand or No.1 portion of the control opening 56, cause the arm 55 to retain the segment 39 in its central position, as shown here, to in turn retain the item totalizer wheels 36 in alinement with the primary differential members 33, to receive the amount of the item set up on the amount keys 28. Near the end of machine operation, the stud 114 (FIG. 7) engages a raised portion 118 of the cam surface 113 to rock the lever 111 clockwise, causing the stud 110 to again engage the surface 189 and impart counter-clockwise movement to the arms 92 and 85, causing the roller 84, in cooperation with the V notch 83, to again restore the totalizer-shift- 7 ing segment 39 to its central, or normal, position, in which the item totalizer wheels 36 are in alinement with the primary differential members 33, as shown in FIG. 2.

After all the items involved in the multiple-item transaction have been entered, under control of the Row 2 control keys 27 (FIG. 1), an item total operation is initiated by depression of any one of the Clerks keys 25 in Row 1. For example, depression of the B Clerks key 25 (FIG. 3) moves its pin 37 downwardly into the path of a stop surface 121, formed in the right-hand opening in the periphery of the totalizer selecting segment 3?. Depression of the B Clerks key 25 (FIG. 5) also causes the pin 37, in cooperation with a cam surface 122, formed in a corresponding opening in the periphery of the control segment 80, to shift said segment clockwise which, through the stud 79, causes the crank 77 to shift the arm 55 (FIG. 3) also clockwise to move the central or No. 2 control portion of the opening 56 therein into alinement with the flat portions of the studs 57 and 58 in the scissors levers 59 and 60. After the arm 55 has been positioned, the cams 71. and 72, through the lever 167, shift the companion links 165 and 162 upwardly to rock the bell crank 65 clockwise, causing the roller 64 to eX- pand the scissors levers 59 and 6%. Expansion of the scissors levers causes the studs 57 and 58, in cooperation with the No. 2 or central control portion of the opening 56, to shift the arm 55 downwardly. This rocks the segment 39 clockwise from its central position until the stop surface 121 thereon yieldingly engages the pin 37 in the depressed key 25, to position said segment 39 in accordance therewith, which, through the gearing shown in FIGS. 2 and 3 and explained previously, shifts the shaft 48 and the sleeve 51 towards the right to aline the B set of totalizer wheels 35 with the primary differential members 33, for actuation thereby. The spring 74 (FIG. 3) permits the companion links 16 2 and 165 to compress sufficiently to maintain the segment 39 under spring tension, thus to retain the surface 121 in yielding engagement with the pin 37 during the time that the selected set of totalizer wheels 35 are being engaged with and disengaged from the primary differential members 33. The No. l totalizer line is provided with an aliner mechanism (not shown) similar to that shown in FIG. 2 of United States Patent No. 2,911,141, for retaining the selected set of totalizer wheels in accurate alinement with the primary differential members during the time that they are being engaged with and disengaged from said members.

The pins 37 in the D and E Clerks keys 25 coact with corresponding cam surfaces on the segment 311 (FIG. 5) to position the central or No. 2 control area of the opening 56 in the arm 55 opposite the studs 57 and 58, exactly as the B control key 25, and the pins 37 in these keys also coact with corresponding stop surfaces formed in openings in the selecting segment 39, to shift the shaft 48 and the sleeve 51 (FIG. 2) from central position towards the right and extent corresponding to said keys 25 to cause the corresponding set of totalizer wheels 35 to be alined with the primary differential members 33. The selecting segment 39* (FIG. 3) is always restored to its central position, where the item totalizer wheels 36 are in alinement with the primary differential members 33, at the end of each machine operation. Positioning of the segment 39 always starts from the central position to shift the shaft 48 the shortest distance from said central position directly to the position corresponding to the depressed Row 1 control key 25, to select the corresponding set of totalizers for actuation.

In an item total operation initiated by depression of the L Clerks key 25 (FIGS. 1, 3, and 5), the pin 37 in said key, coacting with a cam surface 123, formed on the periphery of the segment 8i), shifts said segment full distance towards the right, or clockwise. This, through the crank 77, rocks the arm 55 also clockwise, against the action of the spring 81, to aline the No. 3 or left-hand control portion of the opening 56 with the studs 57 and 58 in the levers 59 and 6t). Depression of the L Clerks key 25 also moves the pin 37 (FIG. 3) into the path of a stop surface 124, formed in a left-hand opening in the periphery of the selecting segment 39. Expansion of the scissors levers 59 and 60, by the earns 71 and 72 and associated mechanism, causes the studs 57 and 58, in cooperation with the left-hand or No. 3 control surface in the opening 56, to shift the arm 55 upwardly to in turn rock the segment .39 counter-clockwise until the stop surface 124 engages the pin 37 in the depressed L key 25 to position said segment accordingly. This positions the totalizer shaft 48 and the sleeve 51 in their proper lefthand positions (FIG. 2) to aline the L set of totalizer wheels 35 with the primary differential members 33, for actuation thereby. Depression of either of the H or K Clerks keys 25 to initiate an item total operation causes the pin 37 therein, in cooperation with the corresponding camming surface on the segment (FIG. 5), to shift said segment the same as the L Clerks key 25, to aline the No. 3 or left-hand control portion of the opening '56 in the arm 55 with the studs 57 and 58. Subsequent clockwise shifting of the segment 39 by the studs 57 and 58 (FIG. 3) causes corresponding stop surfaces in the periphery of said segment to engage the pin 37 in the depressed H or K Clerks key 25 to aline the corresponding set of totalizer wheels 35 with the primary dif ferential members 33.

Depression of the A Clerks key 25, to initiate an item total operation, through the segment 80, alines the No. 2 control area of the opening 56 in the arm 55 :with the studs 57 and 58 and moves the pin 37 in said key into a clearance portion of the right-hand opening formed in the periphery of the segment 39. Operation of the levers 59 and 60 causes the studs '57 and 53 to shift the segment 39' clockwise full distance until its right edge engages a fixed stop (not shown) to aline the A set of totalizer wheels 35 (FIG. 2) with the primary differential members 33.

Depression of the M Clerks key 25, to initiate an item total operation, through the segment 85, alines the No. 3 control area of the opening 56 in the arm 55 with the studs 57 and 58 and moves the pin 37 in said key into a clearance portion of the left-hand opening formed in the periphery of the segment 39. Operation of the levers 59 and 60 causes the studs 57 and 58 to shift the segment 39 counter-clockwise full distance until its left edge engages a fixed stop (not shown) to aline the M set of totalizer wheels 35 with the primary differential members 33.

As each operation initiated under control of the Clerks keys 225 is necessarily an item total operation, in the first part of this operation the wheels .36 (FIG. 2) of the item totalizer are alined with and maintained in alinement with the primary differential members 33 by the mechanism shown in FIG. 7 and explained above. In the first part of an item total operation, the total amount of the items entered in the wheels 36 is cleared therefrom and temporarily stored in the primary differential members, and in the latter part of said operation said amount is transferred from said differential members to the wheels 35 of the totalizer corresponding to the depressed Clerks key 25.

The Sub-Total key 2 6 in Row 1 is provided for reading the amount in the wheels 36 of the item totalizer at any desired time. Depression of the Sub-Total key 26 causes the pin 38 therein to engage a slot (FIG. 3) in the selecting segment 39 and retain said segment in its central position, where the wheels 36 of the item totalizer are held in alinement with the primary differential members 33. Depression of the Sub-T otal key 26 also sets up a condition which causes the amount standing in the item totalizer wheels .36 to be temporarily stored in the primary differential members. During the latter part of an item sub-total operation, return movement of the pri mary differential members 33 re'enters the amount read from the item totalizer wheels 36 into said wheels for use in further computations. The pin 38 in the Sub- Total key 26 imparts no movement to the segment 80 (FIG. upon depression of said sub-total key, and consequently said segment and the selecting arm 55 re main positioned. as shown here, to aline the right-hand or No. 1 control portion of the opening 56 with the studs 57 and 58 in the arms 59 and 60, so that in this case there will be no tendency for the levers 59 and 60 to impart shifting movement to the segment 39.

The above-described operation of the power-operated totalizer-selecting mechanism for the No. 1 totalizers applies only to multiple-item transactions comprising one or more item-entering operations, under control of the Row 2 control keys 27, and a final item total operation, under control of the Clerks keys 25 in Row 1, and these operations, as previously explained, are performed with the total control lever 30 (FIGS. 1 and 7) in Register position, as shown here. The machine is conditioned for totalizing operations, comprising reading and/or resetting operations in connection with the Row 1 Clerks keys 25 and the sets of totalizer wheels 35 on the No. 1 line corresponding thereto, by moving the total control lever 30 to Read Row 1 position, in the case of reading operations, and to Reset Row 1 position, in the case of reset operations. Moving the total control lever 30 to either Read Row 1 position or Reset Row 1 position renders the power-operated totalizer-selecting mechanism inoperative and simultaneously renders effective a manually-operated totalizer-selecting mechanism, which is controlled directly by depression of the Clerks keys 25.

Moving the total control lever -30 downwardly, or counterclockwise (FIGS. 1 and 7), from Register posit-ion to either Read Row 1 position or Reset Row 1 position, rocks the crank 107, the shaft 106, and the companion crank 105 clockwise, causing said crank 105, in turn, to rock the lever 103 counter-clockwise. Counter-clockwise movement of the lever 103 causes the cam surface 102, in cooperation with the roller 101, to rock the lever 99 clockwise, against the action of a spring 127 tensioned between said lever 99 and a stationary stud. Clockwise movement of the lever 99, through the stud 98, shifts the pitman 95 (FIGS. 7 and 8) upwardly, which, through the stud 94, carries the arm 92 upwardly in unison therewith. This moves the downward projection 91 on the arm 92 above and out of the path of the flattened portion of the stud 90, so that subsequent operation of the said arm 92 by the lever 111 will have no eiiect upon the restoring arm 85, other than to tension the spring 96, extending between said arm 92 and the pitman 95. This frees the restoring arm 85 to the action of the spring 87 (FIGS. 3 and 7), which is tensioned to normally maintain the roller 84 in yielding engagement with the Vsshaped notch 83 in the segment 39 and does not interfere with the manual movement of said segment 39 in reading and resetting operations, as will now be explained.

Secured on the shaft 106 (FIG. 4) is an arm 128 having a slot which embraces a stud 129 in a link 130 pivotally connected by a stud 131 to the outer face of a totalizer-shifting segment 126 free on the shaft 40. The stud 129 is arranged to engage a locking notch 132 in the totalizer-selecting segment 39, but is normally retained beneath and out of engagement with said slot when the total control lever 30 (FIG. 7) is in Register position, as shown here. Movement of the total control lever 30 :to either Read Row 1 position or Reset Row 1 position rocks the shaft 106 and the arm 128 clockwise to engage the stud 129 with the locking notch 132 to lock the segments 126 and 39 together, for unitary movement. The segment 126 is normally maintained in its central position, in which position the wheels 36 of the item totalizer are in alinement with the primary differential members 33 (FIG. 2), by an alining or restoring notch 133 in its lower end (FIG. 4), which is engaged by a roller 10 134 in a bell crank 135 pivoted on the stud 86 and urged counter-clockwise by a spring 136, to maintain said roll: er in yielding engagement with said notch 133.

When the total control lever 30 in either Read Row 1 position or Reset Row 1 position and the segments 126 and 39 locked together, as explained above, depression of the A Clerks key 25 (FIGS. 1, 3, and 4) causes its pin 37, coacting with a corresponding cam slot 137 in the periphery of the segment 126, to shift said Segment and the selecting segment 39 from central position full distance clockwise to aline the corresponding set of totalizer wheels 35 (FIG. 2) with the primary differential members 33.

Near the end of machine operation, spring-actuated restoring movement of the starting detent for Row 1, assisted by the spring for the depressed A Clerks key 25, returns said key upwardly, and the pin 37 therein, coacting with the cam slot 137 and assisted by mechanism described below, restores the segments 126 and 39 to their central positions, and this in turn rest-ores the No. 1 totalizer shaft 48 from its extreme right-hand position (FIG. 2) back to its central position, in which the wheels 36 of the item totalizer are in alinement with the primary differential members 33. The arm (FIG. 3), which functions entirely under influence of the spring 87 and 96 (FIG. 7) in reading and resetting operations, and the arm (FIG. 4), which functions under control of the spring 136 at all times, cause their respective rollers 84 and 134, coacting with the corresponding alining notches 83 and 133, to assist the A Clerks key 25 in restoring the segments 126 and 39 to their central positions and to yieldingly retain said segments in said central positions.

Movement of the total control lever 30 to Read Row 1 position '(FIGS. 1 and 7) conditions the No. 1 totalizer engaging and disengaging mechanism for engaging the selected set of No. 1 totalizer wheels 35 with the primary differential members 33 (FIG. 2) near the beginning of machine operation and prior to initial movement of said primary differential members. Initial movement of the primary differential members rotates the selected totalizer wheels to zero and simultaneously sets the corresponding secondary diiferential members, printing wheels, and indicators accordingly. Near the end of machine operation, after the amount read from the selected totalizer wheels has been properly recorded, return movement of the primary dilferential members re-enters the amount into said selected totalizer wheels for further computation.

Movement of the total control lever 30 to Reset Row 1 position conditions the No. 1 totalizer-engaging and disengaging mechanism to engage the selected set of totalizer wheels 35 with the primary differential members 33 near the beginning of machine operation and prior to initial movement of said members, the same as in reading operations, which movement rotates said wheels in a reverse direction to zero and simultaneously sets the corresponding secondary differential members, printing wheels, and indicators accordingly. After the amount cleared from the selected totalizer has been properly recorded, said wheels are disengaged from the primary differential members and consequently remain in a zeroized condition at the end of machine operation.

With the total control lever 30 (FIGS. 1 and 7) in Read Row 1 or Reset Row 1 position, depression of the M Clerks key 25 causes the pin 3? therein, in cooperation with a corresponding camming slot 138 in the periphery of the segment 126, to shift said segment and the totalizerselecting segment 39 from their central positions (FIGS. 3 and 4) full distance counter-clockwise. This shifts the No. 1 totalizer shaft 43 full distance towards the left to aline the set of type wheels 35 corresponding to the depressed M Clerks key 25 with the primary differential members 33 for actuation thereby.

In reading and resetting operations, the depressed Clerks key 25 positions the segment 80 (FIG. 5) in accordance therewith, exactly the same as in item total operations, and said segment 81) in turn positions the selecting arm 55 in proper relationship to the studs 57 and 58 in the scissors levers 59 and 60, as in item total operations. Subsequent operation of the scissors levers 59 and 61) has no effect upon the positioning of the segment 39, as it has already been positioned under control of the segment 126, as explained above.

Depression of any one of the other Clerks keys 25, in reading or resetting operations, cause the pin 37 therein, in cooperation with the corresponding camming slot in the periphery of the segment 126 (FIG. 4), to position said segment in accordance therewith to aline the corresponding set of totalizer wheels 35 on the No. 1 line with the primary differential members 33 (FIG. .2) for actuation thereby.

The Items Sub-Total key 26 is never used in reading and resetting operations in the No. 1 totalizers, and, consequently, means, which functions upon movement of the total control lever either to Read Row 1 position or to Reset Row 1 position, is provided to lock said key against depression.

Secured on the shaft 106 (FIG. 6) is a crank 140, having a stud 141, which engages a slot in an arm 142, free on the shaft 78. The arm 142 carries a stud 143, which engages a cam slot 144 in a locking segment 145 free on the shaft 40. Counter-clockwise, or downward, movement of the total control lever 30 (FIG. 7) to Read Row 1 position of Reset Row 1 position rocks the shaft 106 and the crank 140 clockwise, causing the stud 141 to rock the arm 142 counter-clockwise, during which movement the stud 143, coacting with the lower portion of the cam slot 144, rocks the locking segment 145 also counterclockwise to move an obstructing surface 146, on its periphery, beneath and into the path of the pin 38 in the Item Sub-Total key 26, to obstruct depression of said key during reading and resetting operations in the No. 1 totalizers.

When the total control lever is in Register position, the segment 145 (FIG. 6) is positioned as shown here, so that a slot 147 therein is opposite the pin 38 in the tem Sub-Total key 26; consequently, depression of said key causes said pin to enter said slot to secure the segment 145 against movement during item sub-total operations. Likewise, when the total control lever 30 and the segment 145 are in Register position, as shown in FIGS. 6 and 7, obstructing projections 148 on the periphery of said segment 145 are so positioned that they are to the left of and out of the path of the corresponding pins 37 in the Clerks keys 25 and consequently do not interfere with the depression of said Clerks keys 25 in item total operations. Counter-clockwise movement of the segment 145, upon movement of the total control lever 31) to Read Row 1 position or Reset Row 1 position, moves the projections 148 farther away from the pins 37 in the Clerks keys 25 and consequently do not interfere with depression of said keys in reading and resetting operations in the No. 1 totalizers.

In item sub-total operations, depression of the Item Sub- Total key 26 (FIG. 4) causes the pin 38, carried thereby, to enter a clearance slot 154 in the periphery of the segment 126, said slot being similar to the slot 125 (FIG. 3) in the segment 39, to secure said segment 126 against displacement from its central position.

Clockwise movement of the total control lever 30 (FIGS. 1 and 7) from Register position to Read Row 2 position or Reset Row 2 position rocks the shaft 106 and the crank 1411 (FIG. 6) counter-clockwise, causing said crank to in turn rock the arm 142 clockwise, whereupon the stud 143, coacting with the upper portion of the cam slot 144, rocks the segment 145 also clockwise. This moves an obstructing surface 149, on the periphery of said segment 145, into the path of the pin 38 in the Item Sub-Total key 26 to block depression of said key in Read Row 2 and Reset Row 2 operations. Likewise, clockwise movement of the segment 145, as explained above, moves the projections 148 into the paths of the pins 37 in the Clerks keys 25; with the exception of the M Clerks key, and in this case the obstructing surface 146 moves into the path of the pin 37 in said M Clerks key, to obstruct depression of the Clerks keys 25 during reading and resetting operations in the No. 2 totalizers.

As previously explained, the Clerks keys 25 (FIG. 1) and the Item Sub-Total key 26 in Row 1 and the Department keys 27 in Row 2 are what are termed motorized keys, in that depression of any one of these keys, in addition to its other functions, initiates machine operation by freeing a machine and key release shaft 150 (FIGS. 3 and 7), journaled in the machine framework, for clockwise movement under spring power. This closes the usual switch to the electric motor (not shown) and operates a clutch mechanism (not shown) which clutches said motor to the main cam shaft 73, to effect operation of the ma chine. Near the end of machine operation, the shaft 150 is restored counter-clockwise a slight distance beyond its normal, or home, position, in which it is shown here, to terminate machine operation and simultaneously to release the depressed control and amount keys. Said shaft is then spring-returned to its normal position.

Manipulation of the key release lever 29 (FIG. 1), when the machine is at rest, also rocks the machine and key release shaft 150 (FIGS. 3 and 7) counter-clockwise a slight distance beyond its normal position to release any depressed amount keys for return to undepressed positions by their springs. Operation of the shaft 150 by the lever 29 also releases any depressed motorized keys 25, 26, or 27 and restores the machine-releasing mechanism to unoperated condition, if for any reason the machine fails to operate. Counter-clockwise operation of the shaft 150 and an arm 151, secured thereon, by manipulation of the lever 29, causes a stud 152, in a downward extension of said arm, to engage a forward surface on an upward extension 153 of the lever 11 1 to rock said lever clockwise. The lever 111 in turn operates the arms 92 and 85, when the total control lever 30 is in Register position, as it is in item total operations, to positively restore the segment 39' to central position and simultaneously to release the depressed Clerks key 25 upon failure of the machine to operate. When the total control lever 30 is in Read Row 1 or Reset Row 1 position, the projection on the arm 92 (FIGS. 7 and 8) is out of coacting relationship with the stud in the arm 85; therefore, operation of the lever 111, by manipulation of the lever 29, causes the arm 92 to impart added tension to the spring 96, which, through the pitman 95, assists the spring 87 in imparting restoring movement to the arm 85 and the segment 3-9. Automatic clockwise operation of the lever 111 (FIG. 7) by the shaft and the arm 151, near the end of the machine operation, as explained before, is an irrelevant occurrence, as the cam 72 (FIG. 7) operates said lever 111 at approximately the same time, to impart restoring movement to the arm 85.

Operation It is believed that a full understanding of the operation of the machine embodying the present invention will have been obtained from a perusal of the preceding description; however, a brief resume of machine operation may be helpful and will now be given.

The machine chosen to illustrate the present invention is arranged for what are termed in this art multiple-item transactions, comprising one or more item-entering operations and a final item total operation, and the machine is conditioned for multiple-item transactions by positioning the total control lever 30 in Register position, as shown in FIGS. 1 and 7.

In item-entering operations, the amount of the item is set up on the amount keys 28, after which the proper Department key 27 is depressed in Row 2 to initiate machine operation, during which the amount of the item is entered into the department totalizer on the No. 2 line corresponding to said depressed key 27 and is simultaneously entered into the item totalizer 36 on the No. 1 line (FIG. 2). The item totalizer is always selected and conditioned for adding in item-entering operations. As many items as are involved in the transaction may be entered in subsequent item-entering operations, under control of the Department keys 27.

At any time when it is desired to obtain a sub-total of the items entered during item-entering operations, an item sub-total operation may be initiated by depression of the Item Sub-Total key 26, which causes the totalizer 36 to be read to record and indicate a sub-total of the amount of the items entered therein.

After all the items involved in the transaction have been entered, as explained above, an item total operation is initiated by depression of the proper one of the Clerks keys 25, which causes the item totalizer 36 to be cleared during the first part of said item total operation, and the amount therein transferred to the No. 1 totalizer 35 corresponding to the depressed Clerks key 25. In item total operations, the power-operated mechanism, shown principally in FIG. 3, functions to aline the set of Clerks totalizer wheels 35 corresponding to the depressed key with the primary differential members 33 (FIG. 2) for actuation thereby.

If it is desired to read or reset the amounts in the totalizers on the No. 2 line corresponding to the Row 2 Department keys 27, the total control lever 30 is moved from the register position to Read Row 2 or Reset Row 2 position, as the case may be, and, in reading or resetting operations initiated under control of the Department keys 27, the corresponding totalizers on the No. 2 line may be read or reset to record and indicate the total amounts therein. Likewise, if it is desired to ascertain the amounts in the Clerks totalizers 35 on the No. 1 line corresponding to the Clerks keys 25, the total control lever 130 is moved from Register position to Read Row 1 position or Reset Row 1 position, as the case may be, after which the Clerks keys 25 may be used to initiate reading or resetting operations in the corresponding No. 1 totalizers 35, to record and indicate the total amounts in said totalizers.

In Read Row land Reset Row 1 operations, the poweroperated selecting mechanism for the No. 1 totalizers, shown in FIG. 3, does not function, but in this case, movement of the total control lever to Read Row 1 or Reset Row 1 position couples the power-operated segment 39 to the manually-operated segment 126 (FIG. 4) to render the power-operated selecting mechanism ineffective, and, as a result, the totalizer shaft 48 and the sleeve 51 (FIG. 2) are shifted manually by depression of the Clerks keys 25, to aline the sets of totalizer wheels 35 corresponding to said depressed keys 25 with the primary differential members 33, for actuation thereby.
